Thân xe đồ chơi / Xe đua Pinewood Derby

This is a fast, unique, standard sized pinewood derby model toy car body.  Print it with supports to get the best wheel well shape.  Using the standard pinewood derby kit parts (or equivalent), lightly hammer in the nails to install the wheels for a press fit.  The cylindrical cavity in the middle of the car can be used to add weight.  Have fun!
